A Study on Biological Cathode Strengthening the Degradation of 2,4-Dichlorophenol by BES

Abstract:

In this study, the enhancement of reductive degradation of 2, 4-DCP at biocathode using BES was investigated. It was found that the removal efficiency could be improved with the 2, 4-DCP acclimatization on biocathode microbes. Besides, the reaction rate constant of the degradation trend curve of 2, 4-DCP reached 0.640 and 0.321 in the case of biocathode group and abiotic cathode group, respectively.Moreover, the introduction of biocathode could enhance the electrochemical characteristics of BES, namely, the cyclic voltammetry curve, power density curve and polarization curve, and finally led to the efficient degradation of 2, 4-DCP.
